Lineage II. I was a cunt. GMs really hated me, even heros. Once they callenged all the players of the server to hunt me down (I was lvl 4) but nobody could find me because I was at the limit of the map and everybody was mad.
Then some GMs came and started to teleport me to different places full of those hunters, or with the most powerful creatures of the world, while I was literally pissing myself because of how mad they were.
I never lol'd so hard playing online games; Oh, L2, oh, 2004, those were great times.
It's not nearly as bad after they've nerfed the BAMs. You could literally just grind them to level 60 if you wanted to. Questing is a good way to get exp too, and it's not all that soul crushing. Get exp boosts if you can afford them. You'll be 60 in 2 weeks max if you play a couple hours a day.
I have a couple characters on NA tera [CH] if you want company.
